Answer 1

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

Anything times 0 = 0

If 0 is added to anything, it does not change the amount.

10*x + 0 = 10x

If you are just adding or subtracting, just remove the parenthesis.

Example: 5 + (6 +7) = 5 + 6 + 7 = 18

If multiplying, just multiply. Example:

5(2a) = 10a

I hope this helps.
